explain the correspondence between the position of an element in the periodic table and its capacity of combination (valence), among others the alkali metals, the alkaline earth metals, the chalcogens, the halogens, the rare gases

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.
